I do indeed now have that landscape at 8km sq space centered at the Coordinates you posted, and can provide that as a mesh with a single texture as is the style I do other locations. I can also do Raw files, but only for single sims at this time. If you have a specific shape done from Google earth, I can apply the textures as you see in my other landscapes.

I know that is not exactly what you asked for but that is what I am able to do. I did some Geodesic Domes years ago in SL but not as complex as what you are showing in the link. If you have 3d files I could help out some but any description that complex would just about be such a 3d build as that description.

On Edit- At 256x256m full sim size an 8 KM location is about 30:1 so a 30meter (100') dome would be one meter on the sim. The data set I have calls for an 8km minimum scale, and each Elevation mark (as a shade of gray) represents either 10 or 30m difference in elevation. Blended it works at the scale intended but cutting it up into smaller parts (like zooming into a photo till you see only pixels) leads to so much less detail per each, that it is not a solution.
